    Averaging Numbers (rating system)

    Here is the script I am working on:

    Code:
    <%
    
    n1 = 9
    n2 = 0
    n3 = 0
    n4 = 0
    n5 = 0
    
    
    random_total= n1 + n2 + n3 + n4 + n5
    
    total_score = random_total/5
    %>
    <center>
    <font size="5" color="#FF0000">
    
    <%
    for count = 1 to round(total_score)
    %>
    
    &#149
    
    <%
    next
    %>
    
    <font size="5" color="#000000">
    <%
    for counter = 1 to round((5-total_score))
    %>
    
    &#149
    
    <%
    next
    %>
    
    </font>
    <br>
    <font size="3" color="#000000">
    
    <%= round(total_score) & " out of 5" %>

    With the 5 different ratings above being 9,0,0,0,0 the average rating should be 1 shouldn't it? Maybe my math is all wrong but this average stuff doesn't seem right. If 5 visitors vote 1 out of 5 stars, and 5 visitor votes 5 out of 5 stars, the average should be like 3, with the script above I get 2.... Anyways, if anyone can see something I am doing wrong I would appreciate the help. Thanks.

    If I am reading what you are trying to do correctly...
    you intend for n1 to mean the number of people voting 1, n2 number of people voting 2, etc.

    Which means that to get the average score, you would need to...

    Code:
    n1 = 9
    n2 = 0
    n3 = 0
    n4 = 0
    n5 = 0
    
    
    average_score= ( (n1 * 1) + (n2 * 2) + (n3 * 3) + (n4 * 4) + (n5 * 5) ) / (n1 + n2 + n3 + n4 + n5)
    Assuming thats what you were trying to accomplish...
    Whats the point of a signature?
